Product Description




This low-mid frequency transducer is specially intended for line array applications. It is well known that is very important to reduce the distance between transducers in this kind of systems. Taking into account this design factor, a new basket with a special shape has been developed. This new basket allows the loudspeakers to be placed closer. By the other hand, the 5G40 characteristics have been optimized in order to fit in the most demanding line array designs. This model features a high power handling (100 w AES), an excellent sensitivity (93 dB) and an extended frequency response with very low distortion (thanks to the use of a copper ring). Moreover, its T-S parameters make possible to obtain an excellent bass response when used in small bass-reflex cabinets.

About Beyma

Since 1969 Beyma has been manufacturing extremely high-end speaker systems from its factory in Valencia. These products are create by some of the best audio engineers who enjoy good sounding music. Do not compare Beyma to other brands who import speakers from China. Beyma produce a wide range of solutions in the loudspeakers field. Their products are all underrated. You can amplify any of their speakers with 2 times the amount of the rated power, and they will easily handle all the power!

The accumulated experience as manufacturer of loudspeakers together with their famous Research & Development team have been the key to their success.

Beyma owns and maintains multiple show car vehicles. Their show cars actually use mostly the cheaper Beyma products in them. Their show cars are known to have the cleanest sound. They sound just as good from 200 feet away as if you were sitting in the car. That is the type of quality and engineering that goes into every Beyma product.
